Separately, Science Channel and Discovery Channel issued a statement saying Grant Imahara and Tory Belleci, stars of the TV show "Mythbusters," were in Terminal 3 at Los Angeles International Airport at the time of the shooting incident.

"Both were en route to Delaware for the filming of 'Punkin Chunkin'," according to the statement. "Grant and Tory are safe and being rerouted. Our thoughts are with all those affected by today's tragedy and our gratitude goes out to the members of the LAPD, Airport Police, TSA, and Virgin America staff for restoring safety to the scene."

A Transportation Security Administration agent was killed and several people were wounded in Friday's incident.
